S.H.
I just took my 21 month old daughter in for this very thing last week. She was coughing all day and all night, but at night it was so much worse. She was not getting hardly any sleep. I tried everything, vicks vapor rub on the feet, honey, humidifer, cough medicine, nothing worked. After two weeks of this she started running a fever, so I took her in. Chest x-ray was clear, so no pneumonia, but they felt it might develop in to it, so she got an antibiotic and it really helped to clear it up fast.
